SUPPORT FOR ILLUMINATING WARE Filed Aug. 28, 1940 Patented Oct. 14, 1941 UNITED STATES PATENT FFICE SUPPORT FOR ILLUIVIINATING WARE Hugh J. Claspy, Monaca, Pa., assignor to Phoenix Glass Company, Monaca, Pa., a corporation of West Virginia Application August 28, 1940, Serial No. 354,524

1 Claim.

closed in my application Serial No. 354,525, filed August 28, 1940.

One object of my invention is to provide a shield and a holder therefor of such form that they can readily be applied to various standard forms of lamp structures, and whereby the holders can readilybe applied andvremoved to support and to disengage the light-shielding elements, and without the necessity of employing holding screws, clamping rings or similar devices to maintain the shields in place.

Another object of my invention is to provide an arrangement whereby stock'lengths of shield elements can be employed in connection with lamp tubes of various lengths, rendering un-.

necessary the forming of shield elements of certain particular lengths to fit over each of various lengths of lamp tubes.

As shown in the accompanying drawing, Figure 1 is a side view of an illuminating unit embodying my. invention; Fig. 2 is a perspective view of one of the yokes shown in Fig. 1 as sup- .porting the shield elements, and Fig. 3 is a perspective view, partially in section, of a portion of the structure of Fig. 1.

The invention is shown as adapted for use in a shielding fluorescent lamp tubes or other lamp tubes that are commonly supported in a horizontal position, although certain features of the invention are applicable also to lamps of the other types and to lamps supported in other than horizontal positions.

The numerals 4 indicate hanger rods that usually depend from a ceiling and serve as sup-.

The shield is shown as comprising a plurality of shield elements 9 and yokes or joining rings III. The elements 9 are commonly formed of glass or other transparent or semi-transparent material, and the joining rings l0 may likewise be formed of light-transmitting material, but

I may be of metal where certain ornamental effects are desired.

The shield elements 9 are shown as of curved contour and are supported at their ends by the joining rings or yokes II], the longitudinal edges of the elements 9 preferably extending somewhat above the ledges I and 8, so that streaks of light will not shine through past said edges.

Each of the yokes ID has a rib ll that serves as a stop member for the ends of the sections 9. Flanges l2 are provided on the yokes 10 in position to rest upon the ledges l and 8 of the shield holder 6. The yokes H1 not only serve to support the shield elements 9, but obstruct rays of light which would otherwise pass between adjacent ends of the shield elements 9. The yokes ID are slidable longitudinally of the flanges l and 8 to permit insertion and, removal of the shield elements 9. It will be seen that as many shield elements 9 will be employed as are necessary to enclose a particular installation, and that a set of shield elements of any given length can be employed to cover lamps of various lengths. Usually some suitable form of enclosure will be provided for the extremities of the shield.

I claim as my invention: A shielding device for lamps, comprising a cover plate member of generally channel form,

'mounted in inverted position and having inwardly turned flanges on its lower longitudinal edges, a substantially narrow supporting element of outwardly bowed form but having its extremities extending behind and supported on the flanges and freely slidable longitudinally thereof, a rib on the inner surface of the said element, and lighttransmitting shield elements of outwardly bowed form and arranged in relatively longitudinal alinement, with their adjacent ends extending behind and resting upon the supporting element and abutting the said rib, the longitudinal edges of each shield element extending inwardly past the outermost planes of the flanges, the shield elements being curved on a uniform radius throughout their lengths, whereby they may be cut to desired lengths for assembling with the supporting element.
